With these and other objco s in View, this invontiou es in the Emu features of ioS -' construction, foiiinsfiion, combination and arrsngomeus of psi'ss to no lioroinoftor more fully dosoribod, claimed and iilu'sizmted m 1 4 1 the accompanying drawing, in Wli1ol1:-

Referring to the drawing. the numomi ii designates a bracket, which is adopted to be secured to the side of the Wall. Supported by the bracket is an arm 52. to which is ad jus v31,3; a uociod an arm 3 said -baing disposed in ilOIlZOiliilli position.

bearing 4: in which is rot-stably mounted the trunnion 5 which is it'ormcd upon the upper slid of the vertical bar 6. The trunnion dis odspiod for rotation in the bearing 4 and is hold therein by the cross pin 7,

The tube support Sconsists of a horizontal bar 9 having depending from its ends, bars 10, one of which 18 provided Wlth a bearing 11,.Whils the other is provided with on open bearing 12. To attach the X ray tubo to the support the extension 14:-

ilioifoof is inserted in the bearing 11, afizer.

which the tube is swung so that the we sion 15 thereof is engaged in the boa-ring 12.

The usual cxtensioulG of the tube is 6011- necked to the lower end of the cord 17,' the upper end of which is adopted to be sccurod' to any one of the vertically alined hooks 18" so that the rays from the' tube. cam be di-' rooted iaii the desired anglo upon the paltionts head, said hooks being supported i upon i'ho arm 19 which has its 'lOW'Bl end connected to thoj'ior 9 and its upper and connected to the lower end of the bar 6 by a clamping bolt 20. The clamping boli; 20

can be manipulated so bisto hold the arm 19' at different angular relations to the bar 6, and the bar 6 is rotatably connected to the arm 3 the tube support 8 can describe a circle oroundtho head of the patient so as to dirootsho rays of the tube to the desired spot. By pivotally oonneoting tlio bar 6 and arm 19 it is obvious thattho tube sup-i port can beswung upwardly and out of the Way, and hold in this position in any suitable manner. When-the tube support 8 is v swung to its inoperative position it is obvious that the arms 2 and 3 can be swung against the Wall, as the bi'acket l is mounted upon the clips 21.

Whot is claimed isz- '.;l In a deviooof tho. oisss described; the combination with a bracket, of arms suppiivotsily ported by the bracket, one of said arms-haw;

ing a hole formed in its outer end, a bar having a. vertical pin formed upon its upper and, an srm adjustably connected to tho lower end and arranged to extend vertically through the hole of the bar on a horizontal pivot, means for maintaining the bar m its In testimony whereof, I affix my signature, in the presence of two witnesses.
